SPECIFICATION forming part of Letters Patent No. 621,751, dated March21, 1899.

Application mea April-1,1898. seria No. 676.325. (No model.)

To all whom t may concern:

Be it known that we, GEORGE A. DRAPER and CHARLES F. ROPER, of Hopedale,County of Worcestertate of Massachusetts,have invented an Improvement inSheet-Metal Lays without decreasing the stiffness and rigidityl thereof.

We will now describe one form of lay embodying our invention and willparticularly point out the novel features thereof in the claims.

Figure 1 is a front elevation centrally broken out to save space of aloom-lay embodying our invention. Fig. 2 is an enlarged transversesectional view thereof on the line looking toward the right. Fig. 3 is asectional view on the line an' so, Fig. 1, looking toward the left. Fig.l is a left-hand end elevation of the lay. Fig. 5 is a right-hand endelevation thereof; and Fig. 6 is a perspective detail of one of thebrace members of the lay, to be referred to.

The main or body portion of the lay. is composed of sheet metal bentlongitudinally to form parallel stiening-flanges a a', with aconnecting-web ax, the latter forming a continuous running surface orraceway for the shuttle, the body of the lay being substantially like aninverted trough. At each end the web ctx is longitudinally slotted forthe picker-stickP P', Fig. 1, and at the left-hand end two uprightparallel channel-plates 3 3 are mounted beneath the raceway, one at eachside of the picker-slot a2, (see Fig. 2,) said plates being herein shownas :l-shaped in cross-section. The outer ends of the plates, which formthe sides of the picker-Opening, are held securely in place by metaldistanceblocks Il, (see Fig. 4,) through which and the flanges of thelay-body are extended bolts a3,

closing the end of the lay and strengthening it at the same time. Attheir inner ends the ment of one of the lay-swords A, said braceblockhaving a suitable buer or cushion p' mounted thereon between the plates3 for the picker-stick P on its inward stroke. The block b hastransverse holes therein for attaching-bolts 6, Fig. 1, which passthrough the anges aa' and lirinly connect the laybody and brace-block,and also securing the lay to the sword A. A laterally-extended ear h'projects from the front side of the block, passing through a slot in theflange ot to support the inner end of the front wall c of the left-handshuttle-box, (see Fig. 1,) the other end thereof being supported by andattached to an ear d', extended through flange ct from a bracket d,attached to the inner face of the ange ct by bolts 7 and located betweenthe brace l) and the end of the lay. The bracket cl has a depending footcl2, recessed to receive the picker check-strap S in usual loop form andsecured to a hanger a4, bolted to the rear ange a', the footclzhavingits end outwardly extended at d5, Figs. 1 and 2, beneath theedge of the strap. A lug d4 on the bracket has attached thereto by abolt S an arm d5., y

which acts frictionally on the strap to prevent too freemovement thereofunder the impact of the picker-stick.

The flanges a a and the web aX are cut away to register with atransverse depression b2 in the top of the brace-block b to receive theusual grating g, with which the fillingfork coperates.

At the left-hand end of the lay the flanges a a are reduced in width, asshown in Fig. 1, and at the other end of the lay the flange a issimilarly shaped; but the flange a is out away, as at a6, to facilitatethe discharge of a spent filling-carrier from a shuttle in the adjacentshuttle-box.- y

Back of the path of the picker-stick P a guide-plate e is inserted, heldat its outer end in a block 12, Fig. 5,inserted 4between the flanges aand a at the extreme end of the lay and rigidly secured thereto by bolts13, the inner end of the guide-plate being attached IOO to a brace-blocke, (see dotted lines, Fig. 1,) bolted to and between the flanges of thelaybody and to the lay-sword A by suitable bolts 15. The guide-plate eXhas formed thereon a depending lip e', to which is connected by a linke2 a bar-like casting e3, which supports a lling-guide chute e4 and thepicker checkstrap S', substantially as shown in United States Patent No.596,448, dated December 2S, 1897.

As shown in Fig. 1, the block e has a lug e5 extending through the dange a, to which one end of the shuttle-box wall e is attached, the otherend of the wall being attached to a lug e7 on the guide-plate eX.

Abunter @Sis bolted to the front of the lay in front of the brace-blocke, said bunter serving to operate filling-changing mechanism at theproper' time to eject a spent filling-carrier from the shuttle when inthe ri ght-h and shuttlc-box andto insert a fresh supply of fillingtherein-as, for instance, in United States Patent No. 529,940, datedNovember 27, 189i.

The reed-cap R is attached to the upwardlyextended ends of thelay-swords A A', and the lower ends oi' the reed-dents RX enter a barR', Fig. 3, which is firmly held in the lay in a peculiar manner.

For a portion of its length between the brace-blocks b and e thesheet-metal web or raceway ax is not extended rearwardly for the entirewidth of the web, but is bent downward, as at d10, Fig. 3, and thenrearwardly at L12 to the flange a', the depth of which at such portionis correspondingly decreased. A seat is thus made at the back of the layfor a clamp-bar f, which may be made of metalor wood, having alongitudinal semicylindrical recess for the reed-bar R', the downtnrnedand slightly-concaved part aloof the web bearing against the oppositeside of the bar R'. Two threaded studsj", mounted in the clampbar, areextended forward through openings als in the wall d10 and enter thethreaded shanks of clamp-nuts f2, extended through the front flange a,the inner ends of the nuts bearing on a brace fx, l-1-shaped incross-section, which is bolted to the flange a. It will be seen thatbytightening the nuts f2 the reed-barR' will be clamped between thedownturned part d10 of the web and the clamp-bar f, holding the reedfirmly in place, yet permitting its ready removal, if necessary, thebrace j'X taking up the thrust of the clampbar f.

From the foregoing description it will be obvious that the laycomprises, essentially, a sheet-metal body portion presenting acontinuous raceway for the shuttle strengthened and stiened at its endsand at the points of attachment to the lay-swords by brace-blocksinterposed between the t ront and reariianges of the sheet-metal bodyand rigidly attached thereto.

Below the reed the body of the lay is shaped to form a seat for aclamp-bar, which coperates with a portion of the seat to rigidly holdthe bottom of the reed firmly in place.

Our invention is not restricted to the exact construction andarrangement shown, asl the same may be modified without departing fromthe spirit and scope of our invention.

Having fully described our invention, what we claim, and desire tosecure by Letters Patent, is-

1. A lay for looms, comprising a sheetmetal body portion havin g longitudinal,downturned flanges and a connecting-web forming a continuousraceway, said web having longitudinal yslots for the picker-sticks,lparallel channel-plates beneath the raceway, one at each side of apicker-slot, and transverse brace-blocks interposed between and securedto the flanges, the inner ends of the channelplates being supported bythe brace-blocks.

2. A lay for looms, comprising a sheetmetal body portion bent to formfront and back flanges with a connecting-web presenting a continuousshuttle-raceway, longitudinal slots in said web for the picker-sticks,the web being reduced in width between its ends and bent in a curvedownward, and rearwardly parallel to the main portion of the web, toform a seat in the body portion for the bottom of the reed, and aclamp-bar in said seat having a longitudinal, concave recess opposed tothe curvature of the sheetmetal body portion, to clamp the bottom of thevreed in place.-

3. A lay for looms,- comprising a sheetmetal body portion bent to formfront and back Hanges with a connecting-web presenting a continuousshuttle-raceway, the web being reduced in width and bent downward andrearwardly between'its ends to form a seat, a clamp-bar in said seat, toengage the bottom reed-bar, and means to move the clamp-bar and retainit in adjusted position.

4. A lay for looms, comprising a sheetmetal body portion bent to formfront and back ilanges with a connecting-web presenting a continuousshuttle-raceway, longitudinal slots in the web for the picker-sticks,guide-plates extended longitudinally below the slotted portions, at theside of the pickerstick paths of movement, and brace-blocks interposedbetween andsecured to the flanges of the body portion, the guide-platesbeing attached to the brace-blocks and supported thereby.

In testimony whereof we have signed our names to this specification inthe presence of 'two subscribing witnesses.
